KINETQGRAPHIC APPARATUS.

Application filed @ctober 22,

To all whom it may concern:

Be it known that we, RICHARD H. Pzn'rzscrr and ROBERT l Nrciions. citizens of the l nited States, of the city of Philadelphia State of Pennsylvania, have invented new and useful improvements in liinetographic Apparatus. of which the following is a specification.

Our invention relates to ltinetographic apparatus suitable for a projector motion pictures and for av motion picture came: making photographic exposures in a lrinetographic series.

it is the object of our invention to prov apparatus of the character referred which is used a film or other picture unit support in which the picture units in tlie kinetographic series are disposed in neighboring rows across the.

0 these ends we have provided appar tus by which the film and the lens are nove intermittently and transversely with respect to each other. then longitudinally wispect to each other. and then again transversely, and so on until all. of the picture units of the kinetographic series have been brought in succession into operative relation with respect to the lens or optical axis. for the transverse movements we employ a riablepitch screw feed. with means operative at the end of each transverse movement to feed the film lengthwise to bring the next row of picture units into operative relation. and in conjunction with such apparatus we employ means for preventing longitudinal movement or oscillation of he film except desired times; and we provide also means for preventing transverse oscillation or movement during the time that the film should remain at rest during its transverse movement.

Eur invention resides in apparatus character hereinafter described.

For an illustration 015 one of the forms our invention may take. reference is to be to drawings. in

the accompanying i vertical sectional view. some two. through the s.

5 is a plan view of a part cooperating to prevent longitudinal movement or oscillat-ion or" the film. Fig. 6 is a plan view of the variable pitch screw feed. Fig. 7 is a cross sectional view, some parts in elevation, taken on the line Y Y, Fig. 6, with other parts associated therewith. Fig. 8 is a cross secclonal view on the line Z-Z Fig. 6, with other parts associated therewith. Fig. 9 is an illustration of a modified arrangement of the variable pitch screw feed mechanism.

Referring to the drawings, B is a suitable camera or projector box having the front wall a and rear wall 5.

. Within the box B is the plate 0 held in position with respect to the lugs or projections (Z on the box B, light proofing material 6 intervening between the projections (Z and the plate 0. The plate 0 forms-one wall of a casing having the lower wall 9 resting against or secured to the bottom of the box 'i. Secured to the front side of the wall 0 is the metal spinning 7i forming a housing for the rotary shutter 2' having the are shaped opening y' which, during rotation of the shutter, allows for a predetermined suitable time free light passage'through the lens 7r, which may be for convenience mounted upon the member h, and through the aperture m in the plate a. The shutter is driven by the bevel gear a, journaled in the plate 6, and meshing with the driving bevel gear 0 secured upon the shaft 79, which is in turn driven by the pinion 9 driven by the hand crank 25.

The gear'r also drives. the pinion u secured upon shaft 0) upon which is secured the variable pitch screw feed 10. This screw feed to has two variable pitch screw threads of which the channels a: of one halr have throughout the greater portion of a circumference no pitch longitudinally of the memher to. neighboring channels 00 being connected by the inclined or curved channel portions e which are the only portions having a pitch. At its one end the variably pitched channel 2 decreases in depth as indicated by the rising surface a which rises to suhstantially the height of the ribs between the channels And channel of decreasing at the other end of the slot there is alateral deflection 2' with the rising bottom 2' Disposed parallel with the shaft 4) is the longitudinally. movable shaft (1, provided at its one end with the guiding hole b and shaft a passes through the wall 0 of the casing f. Secured to the shaft a by pin al is a pin wheel 6 carrying at its one end a circumferential series of pins 7 and at its other end a similar series 9 the pins f at one end being staggered oralternated in angular position with the pins at the other end of the wheel 6 Driven with the variable pitch screw feed to is the locking disk or circular rib ii adapted to engage in succession in the circular channels or slots 2' in the wheel 6 The disk 1 is cut away between the taperin points j to a depth to allow longitudinar slots m 7? 0 and the other comprising the three parallel slots p 1 and r il hile one set of these slots will suffice, we may use two sets as shown. The slots of each set are joined by two suitably curved or slanting slots 8 as best indicated in Fig. 5, and each complete slot having pin entry and exit terminals 25 Secured upon the shaft (4 as by pin a is a feeding sprocket wheel '0 having the usual teeth or projections engaging in the marginal perforations 20 in the film which, as shown i Fig. 1, has the picture units arranged in successive transverse rows. F or example, one row comprises four picture units, (though it will be understood that our invention is not limited to this number), the individual picture units being indicated at l, 2, 3 and i, this indicating also their order of sequence in thekinetographic series. 'l he next picture unit in the series is 5 which is in the next row with units (3, l and 8, the series continuing in the next row at 9, 10, 11,12.

etween the sprocket wheel v and the collar a secured upon shaft a is the frame 5 dove-tailed for-transverse movement upon the plate 0 secured upon theplate c. The light aperture m extends through 'the plate 0 which latter has the rectangular extension cZ'-, through which the aperture m continues in size and shape substantially that of a picture unit. the member (Z extending into a transverse slot in the frame 31 and upon the member 6' are the two resilient iihn guides a between which and the door or to F is confined during its i the tilm I la menses movement. lhe door frame 7 is pivoted to the frame 6 at 9 and a latch 71. on the end of the leaf spring 2' serves to hold the pressure plate f in place. T he pressure plate 7' has a transverse aperture as shown in Fig. l, which aperture is substantially similar to that in the member 23 into which the extension (Z projects, such aperture in the member fbeing employed particularly during projection of motion pictures, in which case a suitable light source will be placed to the right of the member f as viewed in Fig. 2. The frame 6 has the upwardly projecting arm to which is pivoted at k a hooked member 712, which engages the hub n on the film storage reel 0 which is moved by member m transversely on the rod 32 supported in the arm Q2. The frame b has also a downwardly extending arm 9* to which is pivoted at s a hooked member 6 which engages the hub a of the film take-up reel c which is movable longitudinally of the shaft to and rotated thereby by the spline a thereon. The shaft 10 is driven by the friction disk 3 pressed by spring a against the face of the pinion b driven by the gear 1*.

The operation is as follows: The gear wheel 1* is turned in a clockwise direction, as viewed in Fig. 3, thereby rotating the shaft '0 and the attached members to and [i in a counterclockwise direction as viewed in Figs. 3, l, 7 and 8. This counterclockwise rotation of the member '10 causes the lowermost pin ,5, Fig. 8, to enter the slot m at 2, the wheel 9 being rotated in clockwise direction at this stage by action hereafter described. By the time this rotary movement of wheel 6 has been completed, the aforementioned pin 7 will have been rotated to position to fully engage in its slot :0, and as the member to rotates, while the wheel a is confined against any rotary movement, as later described, the first inclined or curved portion 31 of the slot 01: will engage the pin f and cause it to move one space to the right, as viewed in Fig. 6, and then the remainder of the circumference of the channel a; at the end of the first inclined slot i/ having no pitch, the wheel 6 will again remain stationary, as to transverse movement, until the neat inclined or curved slot y engages tne when it is stepped another space; and so on for four successive steps or spaces. This stepped transverse movement moves the shaft (1. four spaces transversely, thus carrying the film and the other parts carried by the frame if in four consecutive steps toward the right, as viewed in Fig.

Each of these steps is equal to the transverse width of a picture unit on the film F. During the time that the slot 7 is en-l the pin ,1 the locking plate if is disengaged from the wheel 0, but immediately a transverse step of the wheel c is completed, the member it, by its wedged or lO w sitioned that pointed end channel or slot 2" enters a circumferential I in the wheel 6 positively looking it against any transverse movement until the next slot 31 engages the pin this means the member hlocks the wheel 6 and therefore the film and other parts movable transversely therewith. And while there may he wear upon the slots w, y and the pins on wheel 8 the member 71 insures that the transverse step movements shall begin and end at predetermined unaltering points or positions. When the pin has traversed the entireslot m, it rises on surface 2 inthe bottom of the slot at its right end and simultaneously the next pin 9 enters the slot :0 at 2", such pin g during the partial rotation of the wheel 6 descending the inclined surface 2' fully into the slot whereupon, by operation similar to that above described, the wheel e 'will be stepped four sgaces to the left. T he wheel 3 is rotated half the angular distance between neighboring pins f due to the forcing of through a connecting slot 8 in l and this movement through a slot .9 is caused by another of the pins 7 passing rough the deflected slot .2 in memioer w. of the wheel a uno shaft a has been rotated through ire angle and therefore the film feeding sgrocket 1; has been rotated through i' re angle with resultant pulling down upon he film a distance equal to picture unit, so that a second row 0: picture units is brought into the optical axis or before the lens, and then the step mo emeni: to the left, referred to, occurs so the film is brought successively r or each picture unit in such next row. 7 as the s n finishes its traverse of it rides up upon the surface a sing another partial rota'tion neei c and the shaft or and a further dinally picture a. win f four ement of the film l longitutance equal to the height of a I rid simultaneously the next is slot as at .2 and a further ement to the right follows.

And so on, ilm partalces of four transverse steps the rzght, then one longitudinal stew, ;en four transverse movestep, then four transverse ht, so that all the picture etographic series are brought in succession nto operative relation with the lens in. 'ing this rotation of the gear r by the handle a the shutter i is rotated through e gearing described, and the slot j is su nate length and so noassage of light he- (2 him, or him and is at rest in any of tween re only its positions.

insure locking of the shaft a and therefore the film feeding sprocket '0' against any rotary movement or vibration during any part of the transverse movement of the shaft o and parts attached thereto, the slotted plate is is provided.

As seen in Figs. 4, 7 and 8, while the pin 5/ or f is engaging in a slot in member to another pin or f, or plurality of them, at other parts of the wheel 6 are engaging in the plate 7' A given pin as g will engage the slots m, n and 0 in succession. As stated, one set of these slots in the plate will suflice, though a second set is shown for the second set of pins 7' Each successive pin enters the slot m at its lower left end t and during the four step movements to the right passes longitudinally of the slot 70 toward the right, then as the wheel 6 is stepped around one space, as above described, it passes through the connecting slot 5' to the right end of slot 91 then during the next four steps of movement of wheel 6 to the left, the pin moves along the slot n to the left, then at the next angular movement of the wheel e passes through the second connecting slot 8 into the slot 0 and traverses the same toward the right four successive movements and finally passes out at The slots m and 0 are an angular distance apart equal to the angular distance between neighboring pins so at when a pin has entered the beginning of slot m the pin in advance has entered the left end of slot 0 And at the same time a pin j is in the slot (1 By this means the wheel 6 is prevented from partaking of any angular movement or angular oscillation during the transverse movements of the shaft a: The lateral deflections 2 and at the ends of the slots and at where the pins ,1 and leave such slots cause in effect a transverse movement of the shaft a somewhat in excess of the length of a row'of picture units; the first half of this additional transverse n'iovement forces a pin through the first halt" of a slot 3 causing one half of a rotary step movement of wheel c and the return of a pin in the second half oi the lateral slot .2 or 2' causes continued return movement of the pin through the second half of the slot 8 accompanied by the second half of the rotary step movement of tne wheel 6 Accordingly a pin, as j". will leave one slot as 1), pass lengthwise and upwardly through a connection '8 to a slot f. This curving or slanting connection #4 also renders the apparatus noiseless. it the trauslcr ot' a pin from slot p for example, to a slot 1 were direct or at right angles to the length of the slot p, without additional transverse movement, considerable noise would he produced. lut oy going the roundabout way. through the slanted or curved slot a. such impact and :s'csulting noise is prevented.

During all this operation of the gear '2' by ill) the crank t the re-vvind-reel o is frictionallv driven and itre-winds the film after it has left the film feeding sprocket 0 as indicated in Fig. 2, the film passing over a suitable idler 0 As shown in Fig. 9, the variable pitch screw feed member to may have the part with the slot at disposed on one shaft, while the remaining part 'w having the slot 00 may be disposed upon a neighboring shaft, in which case one set of pins f or g only is necessary, and only one half of the memher is need be used.
